True Detective

McAdams character has huge hang ups on sex which we learn in basically every other scene with her. her reaction to web cam masturbation being the most telling. ie she is a prude. So it stands to reason she would date a normal guy and do normal sex stuff. Then she's like all "put it in my butt" and he's like "wut, you never let me do that before, i'm not ready"

transcripted for you guys:

him: hey, hey, i'm sorry. Look, don't let that ruin it. it took me by surprise is all, ya know, I didn't expect that.
her: forget it. Don't worry about it.
him: come on, we don't have to stop. right, you know, I just wasn't really ready. I didn't think, i mean I don't know. Do you like that?
her: sometimes.
him: Ok. I just didn't think that most women. ya know, you, would...I'm just used to.. Have you done that a lot?
her: let's not talk this to death.

I don't know. I keep watching this scene over and over and the only thing I can take away from it is that's its something he wouldn't expect a prude to do. ie Anal. maybe minor rape fantasy shit like "hold me down" or "pull my hair".

I don't know where the fuck you guys are getting the knives or strap on shit from. it's clear that it's her wanting him to do something to her and that it took him totally by surprise, since she's such a fucking prude.

I was thinking she wanted him to choke/punch/slap her. No way this was about anal, thats too vanilla.

Maybe it was a Cleveland Steamer.

Dead guy looked like the informant from The Usual Suspects.
